Along strict party lines, the Republican-controlled Senate on Thursday night voted to pass a sweeping budget measure—one criticized as both “despicable” and “horrific” for providing massive giveaways to corporations and the super-rich while eviscerating funding for social programs, healthcare, education, and affordable housing.

The measure passed by 51-49 vote, with only one Republican, Sen. Rand Paul of Kentucky, joining every Democrat and the chamber’s two Independents who voted against it. Its approval now paves that way for massive tax giveaways to the wealthy and corporations envisioned by President Donald Trump and the GOP in both the House and the Senate.

“51 Republican Senators just voted to cut Medicaid by $1 trillion and Medicare by $500 billion so that millionaires and corporations can get a tax cut. It’s immoral and despicable,” said TJ Helmstetter, a spokesperson for Americans for Tax Fairness, in a statement immediately following the vote.

Though the budget resolution itself is nonbinding, MoveOn.org’s Ben Wikler notes how the Senate passage on Thursday represents the “starting gun for what might be the most consequential legislative fight of the Trump era: the looting of the U.S. treasury to reward billionaire GOP donors and mega-corporations, at the expense of the rest of us.” And with the Senate resolution now in place, a reconciliation process can begin with Republicans in the House, meaning the GOP can “shoot for a tax bill without a single Democratic vote.”

In the wake of its passage, Sen. Bernie Sanders (I-Vt.)—who earlier this week called the proposal “Robin Hood in reverse” for taking from the poor to give to the rich— said the “Republicans’ budget is not a bad bill. It’s a horrific bill.”

This morning, in response to the Senate’s passage of a budget resolution that would cut nearly $1.5 trillion from Medicare and Medicaid and give massive tax breaks to wealthy individuals and corporations, the Chair of the Patriotic Millionaires Morris Pearl, former Managing Director at BlackRock, Inc., released the following statement:

“The budget just passed by the Senate is not only irresponsible, it is downright cruel. This horrific budget would harm millions of vulnerable Americans all to give even more money to the richest among us. The Senators who voted to cut Medicare and Medicaid by a combined $1.5 trillion just to give millionaires like me a tax cut have betrayed their constituents, catering instead to the demands of their wealthy donors. Both the Senators and their donors should be ashamed to trade the future of this nation for their short-term financial self-interest.”
